A. It is a split collet internal extractor covering 19–22mm internal spreads, used with a slide hammer to remove bearings or sleeves.
A. The collet is pushed into the bearing centre and expanded via a hex nut until it grips, then a slide hammer provides pulling force.
A. The internal spread range is 19–22mm, and it is stamped as size number three.
A. It grips from inside when there is no edge for puller legs to catch, allowing removal from blind holes or recessed bores.
A. It is typically used with a compatible slide hammer and internal extraction kit in the Sykes Pickavant range.
A. Confirm the collet expands evenly, threads on the hex nut and slide hammer connection are sound and the collet body is undamaged.

A. Store it in an organised internal extractor kit case or tray labelled with its size number and range.
